When does a volcano eruption begin?
A volcanic eruption starts with the build up of pressure in the magma chamber. A bulge in the crater may indicate a impending eruption. Earthquakes may also precede an eruption.
Can volcanoes make the earth shake?
Many things can effect, they can ruin the earth and cause lots of problems. For example pollution.
Why are rich countries prepared for earthquakes?
because they can afford to prepare for something that may never happen. Poor countries, they have trouble enough getting through the day. They can't be spending precious money on rare, future events.
How may earthquakes of 6 or more magnitude occur each year?
There's about 140 earthquakes with 6 magnitude or above a year.
What may happen due to the movement of crustal plates?
earthquakes
What instrument measures earthquakes that may precede a volcanic eruption?
A seismograph.

Is the motion of lithospheric plates a major cause of earthquakes?
It is the main cause of earthquakes. However you may get minor earthquakes due to volcanic activity or mass wasting events.
What may precede a volcanic eruption?
Earthtremors.

How do you keep people safe when earthquakes occur?
A strong earthquake may be followed by weaker, but still potentially dangerous earthquakes called aftershocks. Aftershocks may be potentially more dangerous than other earthquakes of the same intensity because some buildings may have been weakened during the main shock.
Do earthquakes occur along all fault lines?
They can do, however some fault lines will have much less activity than others and some fault lines may only have very very small earthquakes (that in the main may only be detected using seismometers).
Why earthquakes cause more damage than others?
The biggest earthquakes do not always cause the most damage if they strike unpopulated areas, or areas where the local infrastructure was built to withstand severe earthquakes. Also some big earthquakes may be high in intensity, but very short in duration, causing less damage.
